# Overview Immersive media (XR) is a term used to describe a set of related technologies that aim to extend our physical reality in various ways. You might be familiar with terms like Virtual Reality (VR) and Augmented Reality (AR), both of which are kinds of immersive media. In this section of the Knowledge Base, you will find information to help you get started with immersive media preservation and steer you towards resources appropriate to your context. If you're new to XR preservation, the recommended route through these pages is to start by reviewing the prompts in the [Initial Assessment](/pimkb/getting-started/initial-assessment.md) section. These will help you characterise the XR material/experience you are working with and then point you in the direction of relevant sections of the Knowledge Base. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
